Application led August 5, 1916. Serial No. 113,399.

To all whom t may concern.'

Be it known that we, WILLIAM C. LEA and JOSEPH C. GEORGE, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Sash-Operating Device, of which the following is a specification.

Our invention relates to a device for operating easement windows, and is more particularly designed for the purpose of operating easement windows which rare hinged to the side of the window frame and open outwardly or inwardly therefrom.

The principal objectof our invention is to produce an operating device of the class described of simple form and construction which may be operated from the inside of the window frame by means of an operating bar which has a movement substantially parallel with the window frame.

Other objects and advantages will appear hereinafter from the following description.

Referring to the drawings, which are for illustrative purposes only:

Figure 1 is a sectional plan view of a window frame showing a sash therein operated by a device embodying a form of our invention.

Fig. 2 is a diagrammatic plan view, partly in section, of the device shown in Fig. 1.

Fig. 3 is a vertical sectional view on line 3a23 Fig. 2.

Fig. i is a ing plate.

Fig. 5 is a perspective view of the operating bar and sash arm connected thereto.

6 designates a sash pivotally connected to the window frame 7 by means of a hinge 8, the upper portion of the sash and upper hinge not being shown, as the sash and window frame are of the common form of oonstruction used for what is well known to the trade as an outside Casement window. The sash when in closed position abuts against the outside of stops 9 on the frame 7, which stops also serve as abutments for a screen 10 connected by means of a hinge 11 to the frame 7, it being understood that the screen 10 in the form shown is on the inside of the frame 7.

The operating device consists in general of a sash arm 12, an operating bar 13, and

perspective view of the locka locking plate 14. The sash arm 12 consists of a sash plate 15 and a sash lever 16, the sash lever 16 being formed as an L-shaped extension to the sash plate 15, the sash lever 16 being oH-set as indicated at 17 so that the plane of the sash lever 16 is slightly higher than the plane of the sash plate 15, so that the sash lever extends through a cut-away portion in the top of the sill 18, as shown at 18', the sill in the form shown being provided with a water check 19. The sash arm 12 is secured to the bottom edge of the window 6 by means of suitable screws 20, the sash being out out as indicated at 21 to receive the sash plate 15, as above described. The sash lever 16 extends under the stool 22 of the window frame and is pivotally connected by means of a pin 23 to the end of the operating bar 13, the operating bar 13 being directly over the sash lever 16 and is provided with an L-shaped extension or handle portion 24 which extends through a cutaway portion 25 formed in the upper edge of the apron mold 26 to the inside of the window frame, the end of the handle portion 24 being provided with a knob 27 by means of which the operating bar is moved for the purpose of operating' the sash, as hereinafter described.

28 designates a pin secured to the operating bar 13 and extending downwardly therefrom into a slot 29 formed in the locking plate 14, one side of this slot 29 -being formed with a series of notches 30 for the purpose of receiving the pin 28 as hereinafter described. The locking plate 141 is secured to the upper face of the sill 18 by means of suitable screws 33.

The device is operated in the following manner:

Then the window is in closed position, as indicated in full lines in Figs. 1 and 2, the operating bar is placed in such position that the pin 28 thereon engages in the notch 30 in the locking plate 14 nearest the sash hinge. The pin 28 being engaged-by the sides of the notch vis locked therein against lateral movement and the sash lever is prevented from moving, and the sash is held against the stop 9 until the operating bar is moved inwardly to bring the pin 28 into the slot 29.

It is to be noted that when the parts are in the position just described that the pin 23, or the pivotal connection between the sash leyer 16 and the operating bar 13, also the handle 24.- of the operating bar 13, are all inside the hinge 8 or pivotal connection of the sash to the window frame.

It will also be noted that the sash lever 16 and the operating bar 13 are substantially parallel, and any attempt to open the sash would exert a direct pressure of the pin 28 against the side of the notch in which the pin is engaged.

lVhen it is desired to open the window, the handle 24 is pulled inwardly so that the pin 28 enters the slot 29 in the locking plate, and when in such position very little pressure is required to move the operating bar which in turn operates the sash lever to swing the sash outwardly on the hinge 8, and when the sash is in the desired position, suoli for instanceas is illustrated in Fig. 2 in dotted lines, the handle 24 is moved so that the pin 28 engages one of the notches 30 in the locking plate 14, as indicated in dotted lines in Fig. 2, and when in such position anyT manipulation of the sash is prevented by the engagement of the pin 28 in the notch in the locking plate until the handle 22 is operated to bring the pin 28 into the slot 29 in the locking plate 14, as above described.

The dotted position of the sash and parts in Fig. 1 illustrates the sash in its full open position, and it is to be noted that the pivotal connection 28 between the sash lever 16 and the operating bar 13 are inside of the pivotal connection between the sash and the window frame.

It is to be particularly noted that the knob 27 on the operating bar travels parallel to the tace of the window, such construction being particularly desirable as the knob 27 is at all times substantially under the stool of the window frame and does not move in an arc beyond the :tace of the stool During the movement of the operating bar 18, the pivotal connection with the sash lever 16, that is, the pin 23, swings in the arc of a circle and with a window frame construction, as shown in the drawings. The upper edge of the apron 40 and apron mold 26 is cut away as indicated at 41 in Fig. 1 to accommodate such movement.

In many instances where the easement is placed on the outside of the window frame, a screen as shown is placed on the inside of the frame, and with old forms of sash latches it is necessary to first open the screen so that the easement may be reached. Viith a device of the torm hereinabove described, the easement may be operated from the inside of the frame without opening thel screen, and the handle on the operating bar forms an inconspicuous means for accomplishing the operation of the Casement, the movement of the handle and knob thereon being parallel with the face or the frame during such operation. It is to be understood, however, that the device may also be used on a easement, on the inside of the frame, adapted to swing into the room without departing from the spirit of our invention.

In combination, a window frame, a sash pivotally connected thereto, a sash arm rigidly mounted on said sash, and an operating bar pivotally connected to said sash arm, said bar being slidably mounted in the trame and adapted to move substantially parallel with the face of said window frame for swinging the sash.
